2012 Mercedes-Benz C-Class Replacement - Fast, Affordable & Professional
Got a call from a guy out in the Saticoy area of Ventura. His 2012 C250 had one working key left, and the chrome shell was cracking right along the seam where the blade meets the head. He'd been babying it for weeks, holding it together with electrical tape.
He told me the dealer quoted him a two-week wait because the key had to be ordered from Germany, then cut and programmed at the service bay. Two weeks with one taped-together key on a car he drives to work every day.
I showed up with blanks and my IR programming setup. The W204 key system runs through the EIS module, which stores the key profiles, and the ESL steering lock, which has its own separate authorization step. With a working key present, adding a spare is pretty quick. I read the EIS, generated the new key data, cut the HU64 blade on my portable machine, and programmed the fresh IYZ-3312 fob on the hood of his car.
Tested all four buttons. Locks, unlock, trunk, panic. Then the start cycle, watching for the immobilizer light to drop. Clean start, no hesitation.
He peeled the tape off the old key and just looked at it like he couldn't believe that thing had been his only way to drive for three months. I told him to keep it as a backup. New shell, transplant the board, and he'd have two solid keys.
Whole thing took about 20 minutes, on site, for a fraction of what the dealer wanted.
